Upgrade IL.SDK version, disable generating of generate dependency file & custom message for restore tests

[Anipik]

Fixes #40159
Fixes #32205

• Upgrade Microsoft.NET.Sdk.IL to get CompileDesignTime target.
• Added CheckVSRestoreRequirements for build being failing due to restore not being done correctly for tfms with platforms. For all other projects restore from the VS will succeed and error wont be triggered.
• setting GenerateDependencyFile to false. A couple of projects were failing in this target due to some references being not set properly for unix configurations. The design time build provide some information but it was not enough to drill into. However, just adding this condition resolve this error, and we are able to run and build all the projects.
• closing the duplicate runtime issue because the message needs to be fixed by the nuget. We have added the suitable features so that this error does not have any effect on the vs experience. As the restore is not run as a part of target, we cannot edit the error message.

This is true, but project changes that work in VS and don't require a vertical build (EG: adding a reference) would not be reflected in the deps file if we disable it. Disabling in this way will make the build seem flaky. Can you elaborate on what errors you were seeing?

[ViktorHofer]

I agree with Eric. This would be a step backwards as we try to enable VS builds without an initial root build. Also disabling deps generation could easily influence test execution as xunit loads the test's deps file. I would very cautious about that.

i debugged more and found the problem, its basically we are building all the tfms in vs but some of the project references are not build for some tfms like *-unix tfms.
i did a multiple scans over all the sln to check we didnt miss anything. There is not a good way to test this as we need a clean build for every project.
We need to add a ci protection here and a better way to catch these errors.

[ericstj]

This error text doesn't match the condition. It's saying the project has platform specific TFMs, yet the condition is only checking if the assets file is missing.

[ViktorHofer]

Is that sufficient? Don't you also need to disable NuGet restore in the Nuget restore settings inside VS?

[ericstj]

Right, that's required to prevent the package manager error (for the cases where it would fail) and then you probably want an error like this that tells folks to run from the commandline.

Is that sufficient? Don't you also need to disable NuGet restore in the Nuget restore settings inside VS?

i don't want to do that because that will disable the restore for all the tests that are not platform specific.

[ericstj]

Can you put a condition on the property which disables restore?

[Anipik]

we use a nuget.config file to disable restore for the sln and i was not able to conditionally exclude the nuget.config file from projects.
We can always add the nuget.config to the individual projects rather than libraries root but that would be a lot of duplication.

You are missing the Version.Detail.xml update for the IL Sdk. Also please remove the solution file updates from the PR.

closing this one as the most of it is addressed in other prs
